Coincidentally, today I was at the Detroit Institute of Arts to see Heather Henson's Ibex Puppetry group do Celebration of Flight. This is a pretty cool show involving puppets, kites, and things that are half way between. It's not like Muppet stuff, its more avant guard and hippie like (ie: the closing theme was by The Polyphonic Spree). I never knew there was such a thing as a "expert kite flyer" until today. The weather was perfect and basically it was totally great.
Of course she dedicated the performance to Jerry Nelson. The Muppets were a big thing for me as a kid. Not so much Sesame Street but more The Muppet Show and The Muppet Movie. Particularly Jerry Nelson related was Emit Otter's Jug Band Christmas (he was the voice of Emit) which is now starting to gain some notoriety after 25 years of comparative obscurity.
I hope some day programing for kids will regain the spirit of the 1970s, and lose some of the crack addled hyper color noise that contemporary shows are swimming in. More Rainbow Connection, less Elmo, and treating kids respectfully and not treating them like helpless idiots.
